SRI/USEPA-VS-GHG-VR-21 April 2003 Prior to installation of the IR PowerWorks, the facility used two gas-fired boilers to generate hot water for space heating and DHW throughout the complex. The two boilers are Weil-McLain Model Number BG 688 units, installed in 1996. Each boiler has a rated heat input of 1,700 thousand British thermal units per hour (MBtu/hr), gross output capacity of 1,358 MBtu/hr, and a net hot water production rate of 1,181 MBtu/hr. The IR PowerWorks is configured in-line with the boiler supply and return fluid (PG) lines (working fluid is a mixture of 16-percent propylene glycol in water). Testing commenced on August 14, 2002, and was completed on August 21, 2002. It consisted of a series of short periods of “controlled tests” in which the unit was operated at full load (the IR PowerWorks unit tested did not have the capability of intentionally modulating power output). Three test replicates were conducted during normal site operations regarding heat recovery and use. During these tests, the facility boilers were thermostatically controlled to maintain desired supply PG temperature. A second set of three tests was conducted at full power with the boilers turned off to demonstrate the unit’s ability to produce more heat. These controlled test periods were followed by six days of extended monitoring to verify electric power production, heat recovery, power quality performance, and efficiency during an extended period of normal site operations. During this period, the IR PowerWorks System operated 24 hours per day at full electrical power output and normal heat recovery rate. The classes of verification parameters evaluated are: Heat and Power Production Performance Emissions Performance (NOX, CO, THC, CO2, and CH4) Power Quality Performance Evaluation of heat and power production performance includes verification of power output, heat recovery rate, electrical efficiency, thermal efficiency, and total system efficiency. Electrical efficiency was determined according to the ASME Performance Test Code for Gas Turbines (ASME PTC-22) and tests consisted of direct measurements of fuel flow rate, fuel heating value, and power output. Heat recovery rate and thermal efficiency were determined according to ANSI/ASHRAE test methods and tests consisted of direct measurements of heat transfer fluid flow rate, differential temperatures, and specific heat of the heat transfer fluid. Ambient temperature, barometric pressure, and relative humidity measurements were also collected to characterize the condition of the combustion air used by the turbine. The evaluation of emissions performance occurred simultaneously with efficiency determination at both normal site conditions and with site conditions altered to enhance heat recovery. Pollutant concentration and emission rate measurements for nitrogen oxides (NOX), carbon monoxide (CO), total hydrocarbons (THC), carbon dioxide (CO2), and methane (CH4) were conducted in the turbine exhaust stack. All test procedures used in the verification were U.S. EPA Federal Reference Methods. Pollutant concentrations in the exhaust gas are reported in two sets of units-parts per million volume, dry (ppmvd) corrected to 15 percent oxygen (O2), and mass per unit time (lb/hr). The mass emission rates are also normalized to turbine power output and reported as pounds per kilowatt hour (lb/kWh). Annual NOX and CO2 emissions reductions for the IR PowerWorks System at the test site are estimated by comparing measured lb/kWh emission rates with corresponding emission rates for the baseline power and heat production systems (i.e., systems that would be used if the IR PowerWorks System were not present). At this site the baseline systems include electricity supplied from the local utility grid and heat from the facility's standard natural gas boilers. Baseline emissions for the electrical power were determined following Ozone Transport Commission guidelines. Baseline emissions from heat production are based on EPA emission factors for commercial-scale gas-fired boilers. S-3PDF Image | THE ENVIRONMENTAL TECHNOLOGY VERIFICATION PROGRAM
